Neosho River Bridge

The Neosho River Bridge, near Hartford, Kansas, United States, was built in 1926. It was listed on the National [Register of Historic Places] in 1983.
It consists of two reinforced concrete rainbow arch spans, or "Marsh arch" spans, and carries a wide roadway across the Neosho River. It is located east of Hartford on what was described in 1982 as a county road, and in 2019 is known as 19th Ln.
The bridge design was the work of James [Barney Marsh]. This example is just one of 72 rainbow arch bridges built in Kansas, but was assessed to have a good chance of survival due to its relatively obscure location.
